Sirtuins are emerging as key regulators of many cellular functions including metabolism, cell growth, apoptosis, and genetic control of ageing. In mammals there are seven sirtuin analogues, SIRT1 to SIRT7. Among them SIRT3 is unique because this is the only analogue whose increased expression has been found to be associated with extended lifespan of humans. SIRT3 levels have been shown to be elevated by exercise and calorie restriction. Although the role of SIRT3 in cell biology is only beginning to be understood, initial studies have shown that SIRT3 plays a major role in free fatty acid oxidation and maintenance of cellular ATP levels. In the heart SIRT3 has been found to block development of cardiac hypertrophy and protect cardiomyocytes from oxidative stress-mediated cell death. Similarly, SIRT3 has been reported to have tumour-suppressive characteristics. In this article, we review the known effects of SIRT3 in different tissues and relate them to the protection of cardiomyocytes under stress.
